3 years ago Hey @LucasThole - just had a look at this issue. I agree. It seems the mounted mythical cape "stole" the duplicate property - as they both share the exact same name and the mounted version has a lower item id value.
This is an easy fix in the project and I will make the change after the next game update. Thanks for reporting the issue! Will close when it is resolved.
The 'Mythical cape' (id 22114) on the equipment endpoint has its duplicate value set to 'true'. I believe this should be changed to false as this is not a duplicate.
